Real Madrid are playing for a spot in the Champions League quarter-finals in a classic that promises to be an epic battle at the Metropolitano. With the narrow 2-1 advantage, Madrid arrive with doubts, especially concerning Mbappé.
But the big surprise is neither Endrick nor Arda Güler. There is a dark horse in the white team who could play a key role in this decisive match.
Mbappé, the Big Doubt Until the End
The French forward remains in doubt after the blow he received to his ankle against Rayo Vallecano. Although he scored in that match, his performance left doubts. Since his display against Manchester City, his level has dropped, and Madrid need him at 100% to overcome the tie.

Ancelotti didn't want to give clues in the preview and assured that he will decide his squad on the day of the match. However, everything points to him being a starter if he travels.
Courtois and Rüdiger, Luxury Reinforcements
The good news for Madrid comes in defense. Thibaut Courtois and Antonio Rüdiger are back. The Belgian, although still without minutes this season, could be included in the squad.
In contrast, the German center-back is ready to play and will reinforce a defense that suffered in the first leg.
Additionally, Jude Bellingham returns after serving a suspension. His presence is key in the midfield, as the Englishman has been one of the team's most decisive players this season.
Ancelotti's Surprise
With Mbappé injured and Endrick still in Brazil, many expected Arda Güler to have his chance. However, the big surprise could be Brahim. The Spanish forward, key as a game-changer this season, could shine in a physical and aerial duel.
Ancelotti's plan could involve strengthening the attack with a target forward to capitalize on crosses from Vinícius Jr. and Rodrygo. Brahim, with his height and ability to hold defenses, fits perfectly into that approach.

A Packed Metropolitano
On Atlético de Madrid's side, Diego Simeone will have all his players available. Koke, Rodrigo De Paul, and Clément Lenglet have been included in the squad after recovering in time. The red-and-whites are confident in making history and eliminating Madrid from the Champions League, something they have never achieved.
The atmosphere will be intense at the Metropolitano, with the Atlético fans pushing from the first minute. Madrid, however, have already shown on many occasions that they know how to endure on big nights.
